JSON vs. CSV: Which Format Should You Use?
Both represent the same tabular data, but the two formats aren't interchangeable — here's how to tell which one fits your situation.
| JSON to CSV | CSV to JSON | |
|---|---|---|
| Structure | Nested objects and arrays, any depth | Flat rows and columns only |
| Human readability for large tables | Verbose — every row repeats every key name | Compact — column names appear once, in the header |
| Opens directly in a spreadsheet app | No — needs conversion first | Yes |
| Best for | API responses, config files, nested/hierarchical data | Spreadsheet data, bulk import/export, anything already tabular |
